OPERATION
1. When the lift control is in neutral position
•
The oil from the pump enters chamber a and from here flows into passage b .
•
At the same time the oil flows into chamber c of the flow control (1) through passage d .
•
This causes the spool to shift to the right until the connecting passage between chamber a and passage b is closed.
•
The pressure in chamber e caused by the weight of the implement mounted on the linkage (e.g.: plough), keeps the
check valve (2) closed, thereby ensuring that the lift maintains its position.
•
The chamber e is thus a closed chamber that prevents any uncontrolled movement of the lift.
•
The pressure in chamber e also acts on the antishock valve (3) that eliminates any pressure surges caused by jolting
of the implement during work or transport.
